SIADH lab findings (serum and urine Na and osmolality)`
hyponatremia low serum osmolality high urine osmolality elevated urine sodium low serum uric acid
euvolemic
causes of SIADH
meds (SSRIs, NSAIDs, carbamazepine) lung disease CNS disturbance (trauma, stroke, hemorrhage) ectopic ADH-small cell lung cancer pain

short term treatment of severe hypercalcemia (>14)
saline hydration
calcitonin
avoid loop diuretics unless HF
long term treatment for hypercalcemia
bisphosphonates
severe hypercalcemia presentation
weakness
GI distress
neuropsych sxs
volume depleted
